PHOTOGRA2HIC CAMERA.

Application led March 31, 1926. Serial No. 98,891. j

This invention relates to a photographicl roll film camera and consistsin the provision of means for holding in said camera a plurality of filmrolls as well as means for unwinding such films separately for exposure.The invention is illustrated in the accompanying drawings which show thepreferred form of construction.

Fig. 1 represents a sectional ofthe camera.

' Fig. 2, a section on the line II-II `of Fig. 1,v and n j Fig. 3, across-section on the line III-H1 of Fig. 2. Fig. 4 is a perspective viewof a detail.

The camera casing 1 has at one end a film carrier composed of a shaft 2and two discs 7 and 8 which are fixed to said shaft. One end of theshaft projects through the camera casing and is fitted with a thumbplece3 i whereby the shaft can be turned. A disc 4 which turns with theshaft, is fitted with a plurality of equidistant aperturesfor thereception of a pin 6 carried by a spring. 5. The latter is secured atone end to the caslng 1 and serves to lock the shaft in differentpositions of rotary adjustment. A plurality of films 40,7applied`together with their protective backing strips to spools 37 in the usualmanner, is mounted between the discs 7 and 8. To hold lthe film rolls inposition the disc 7 is provided with axially adjustable pivot pins 9which are controlled by springs 10, and the disc 8 is fitted with smallyshafts 11 which can be rotated in opposition `to springs 12. The filmrolls are held between the pinsr9 and the shafts 11 both-of whichproject -through the discs i7 and 8. One end vplatey 39 of the spool 37has a round recess for the receptionof the pvot `pin 9, and theother endplate 38 has a square `recess vfor the reception of the square end 13 ofthe shaft 11 which latter, there-y fore, becomes coupled to `the spool.The arrangement is such that the film unwinds in opposition to thespring 12. The film, or rather its protecting strip, carries at itsouter vend a thin rod 42 which extends be front view spools may beformed with notches 45 l(Fig. 2) for the reception of the rod 42 whenthe films vare lpacked away.

At the opposite .end vof the lcasing 1 v'a take-up roller 30is arranged.The latter is composed of a hollow cylinder which is provided with alongitudinal slot 31 ex tending to the center of the end plates 29. Theroller is embraced vby guider plates -31 within ywhich it can berotated, these plates being connected to the casing .1. Springs 32normally engage notches 32 in the end plates 29 of fthe roller so as tohold the latter normally with the slot facing upwards. Normallysupported in the slot of the roller isa shaft 22 which `carries twodiscs 23 and 24'arranged so as to cover the-end yplates 29 of therollerv30. -Eachof these discs is fitted Y on its inner side with twospaced projections 27-and 28 which normally extend into the' slot'of theroller 30. The shaft 22 and its discs can be lifted off .the roller .30for which purpose a U-shaped frameA 19 is provided. The latter movesvbetween two parallel walls 1,6 and 16 onf thecasing 1. It has acentrally disposed handle 18 which projects from `the casing through aslot 17 in the wall 16. The 'end members 20 and 21 ofthe frame lmove inlaterally disposed slots 15 in thelwallfl and-are in rotatableengagement, one with the projecting end of the shaft 22 the other with aboss 25 formed centrally onthe disc 23. A spring 26 on the member 20engages a notch in the disc 23 andfholds the discs23 and 24 normallywith the projections 27 and 28 in the uppermost position. thread for thereception of a high-pitched screw 34. The Alatter is slidably guided ina sleeve 33 on the casing 1 and is normally held by a spring 36 out'ofContact with the boss 25. The screw has a milled head 35 whereby it can`be pushed into engagement with its screw socket in the boss 25 and usedforturning the take-up roller.

The modus operandi is as follows:

The boss 25 has a female screw-A Before an exposure, vthe pin `6 isreleased from fthe disc 4, and the film carrier is turned to a positionwhich is intermediate between two of those in which it vcan be locked.Thenthe handle 18 is raised in its slot so as to lift the shaft 22 andits disc from the roller 30 and place the discs against the filmcarrier. The' projections 27 and 28 of the discs 23 and 24 will thenbesituated lrelative to the path of the rods f2 so that, on the filmcarrier being restored to a locked position, the projections willreceive the ends of the rod of one of the films between them. If now theframe 19 is restored to its initial position, the rod 42 will bevcarried along by the projections 27, and the'film will be unwound inopposition tothe spring 12. The rod enters the slot in the roller 3()together with the projections, and the roller can then be used forfurther unwinding of the film. rIhis is effected by means of thescrew'34 which is pushed into engagement -with the boss 25 and turned'inthe direction of the screw-thread. Ledges 43 vsupport the film and holdit in the focal plane. If the film is long enough to receive more. thanone picture, suitableknown means are provided f for indicating theamount of unwinding for each picture. y Thev springs32 and 26 tend,`

' this direction, and the screw then leaves the boss 25 and sets theshaft22 free. Then the latter can be raised by means of the frame 19 soas to allow the film and its protecting strip to re-wind completely onto the spool, whereupon the carrier is yturned so as to place anotherfilm in position for use.

Exposed films can be removed from the carrierfor development wheneverrequired, and new films can be inserted. Y

Depending on the size of the discs 7 and 8 and of the film rolls, anynumber of films may be accommodated in the carrier in this manner.

The construction of the device may be varied vwithout departing from thespirit of the invention.
